The simple form of |Hoff equation is: Il = [B]RT In this equation the [B] is the molar concentration of solute. So: m [B] M,V Where c, the mass concentration of the solute is in the total volume of solution and Ma is the molar mass of the solute. This equation can be replaced in the previous one to get: RT II =; In this equation molar mass of given solute can be detemined from the slope of the II vs cg plot. This equation applies only to solutions that are sufficiently dilute to behave as ideal-dilute solutions. In the case of non-ideal solutions, however, the extended formula is: Il = [B]RT{1+ k. [B] + n. [B]² + .-.} Biological macromolecules dissolve to produce solutions that are far from ideal, but we can still calculate the osmotic pressure by assuming that the van't Hoff equation is only the first term of a lengthier expression: II [B]RT(1+b.
